If a window opens on the desktop (a message over MSN or Steam Friends, or a program automatically updating itself), XP minimises my game to the taskbar. This is pretty infuriating when trying to play TF2
, especially since I can't use the Steam community features ingame without the game minimising itself (Steam creates message/chat room boxes on the desktop as well as ingame for some reason).
Anyone know how to stop XP focusing on new windows or interrupting full-screen applications?
